Update 2010-10-30: Changed the initial setup to use gbp-clone.
I’m now officially the maintainer of Licq’s Debian packages. Since I’m not a real Debian maintainer, I’m very grateful to Joel Rosdahl who is my sponsor.
Version 1.3.8-1 is coming to a mirror near you as I write this.
The package source is kept in my git repository. To build the package from the git repository, install git-buildpackage and pristine-tar then follow the instructions below.
Initial setup:
% gbp-clone --pristine-tar git://git.ejohansson.se/debian/licq.git
% git clone git://git.ejohansson.se/debian/licq.git
licq % cd licq
licq % git checkout -b pristine-tar origin/pristine-tar
licq % git co master
To build the latest version:
licq % git-buildpackage --git-export-dir=../build-area
To build a specific version:
licq % git-buildpackage --git-export-dir=../build-area --git-export=debian/1.3.8-1
The final packages will be available in ../build-area.
Later on when you wish to update:
licq % git pull
licq % git-buildpackage ...
The next version will have qt4-gui.

Found this useful command on brain-dump.org. Posting it here for my own reference:

To enable Wake on LAN on a Asus P5E-V motherboard under Debian you can do the following. Since I have a Asus motherboard, that’s the only one I’ve tested, but except from the BIOS (which may differ a bit), the instructions should be the same for all motherboards/NIC that supports Wake on LAN.
In the BIOS, enable “Power on by PCIE device”.
In Linux, first install ethtool and then check that Wake on LAN is supported by running the following command:
root@host$ ethtool eth0
...
Supports Wake-on: g
Wake-on: g
...The output should contain a ‘g’ to indicate that the device can be woken by sending it a “magic packet”.
Enable Wake-on by running:
root@host$ ethtool -s eth0 wol g
Since this command must be run on every boot, add it to /etc/rc.local.
root@host$ cat /etc/rc.local
...
ethtool -s eth0 wol g
exit 0
As the last step we must make sure that halt doesn’t disable the network device. This is done by adding this line to /etc/default/halt:
We also need the MAC address to send the magic packet to.
root@host$ ifconfig eth0
eth0 Link encap:Ethernet HWaddr 00:1e:8c:cf:d0:bb
...
Then shutdown the computer. On an other computer, install e.g. wakeonlan and run:
user@other$ wakeonlan 00:1e:8c:cf:d0:bb
The computer should now start.

Found a very interesting C++ site the other day: C++Next. I highly recommend it if you’re interested in “the next generation of C++”.

Licq 1.3.7-rc1 was announced a few days ago. To quote the announcement:
Licq 1.3.7 contains many bugfixes, and several new features in the Qt4-Gui such as spell checking and configurable keyboard shortcuts.
Download it from the usual place.

After a long time offline, git.ejohansson.se and svn.ejohansson.se are finally back online. They are served from my NSLU2 machine (running Debian) so they are not the fastest loading pages out there.

My mother and father have two computers: a workstation with Windows XP and a laptop with Windows Vista. Yesterday I found a program that made it very easy to keep them both synchronized, i.e. to have all documents and pictures available on both computers. The program, made by Microsoft, is SyncToy v2.0.
I don’t normally write about Windows here, but this program was so good I figured I’d let you know about it. I have it set up to synchronize all files on the desktop and in My Pictures. Both computers share their desktop and My Pictures directory, allowing others to write to them. SyncToy is then set up with two folder pairs, one for the desktop and one for My Pictures. Both computers have the same configuration so that the synchronization can be initiated from any one of them.
To make it easy to synchronize, I created a shortcut on the desktop that runs SyncToyCmd.exe -R (to do the actual synchronization, for all folder pairs). SyncToyCmd should normally be run as a scheduled task, but since both computers must be turned on for the synchronization to work, I opted for a shortcut instead.
Combined with Picasa, they can now offload pictures from their digital camera to any one of the computers and then simply synchronize them. Sweet!

I recently had a lot of problems connecting my Nintendo Wii wireless to my girlfriend’s Netgear router (WNR834B). The router was configured to use WPA-PSK [TKIP] + WPA2-PSK [AES] with a fairly long pass phrase (ASCII characters). It worked very well with my iBook (Mac OS X) and worked most of the time with my girlfriend’s laptop (Windows Vista). But it seemed like Windows used the WPA variant instead of WPA2. It just didn’t connect when forcing it to use WPA2. And the Wii would only connect if we turned encryption off. Not acceptable!
We tried many things to get the Wii to connect, without any success. In a last attempt we tried changing the pass phrase to a 64 characters long hexadecimal pass phrase. That did the trick. Both the Wii and both laptops now connect without any problem. So if you are having problems connecting your Wii to the wireless network, try changing the pass phrase to consist of hexadecimal characters (0-9, A-F) only. For WPA/WPA2 it must be exactly 64 characters long.

A very interesting read about the serious vulnerability in DNS discovered by Dan Kaminsky earlier this year: An Illustrated Guide to the Kaminsky DNS Vulnerability. Recommend read if you are interested in security. Should be possible to understand even for people without prior knowledge of DNS.

Just installed WP-Syntax, a WordPress plugin for highlighting code. The first test will be this short elisp code I wrote to strip trailing whitespace from all lines in a file.
(defun strip-trailing-ws ()
"Strip trailing whitespace from all lines"
(interactive)
(let ((cur (point-marker)))
(goto-char (point-min))
(while (re-search-forward "[ \t]+$" nil t)
(replace-match "" nil nil))
(goto-char (marker-position cur))))
